Got a little blister on ankle that might be a mosquito bite, it’s open & itches like crazy, band aid on & small clear fluid coming out, what is it?

In brief: Blister

Since there is itching it may be a bite or a very localized contact dermatitis such as poison ivy.
At this time, keep the lesion clean,pat dry and apply a cortisone type cream to reduce itching. Spreading redness and warmth would suggest secondary bacterial infection which could need both topical and oral antibiotic. See MD as needed.
